HONGEN 3L/min Membrane Protable Oxygen GeneratorHONGEN 3L/min Membrane Protable Oxygen Generator was designed with a extra slim concept with the reduction of weight to 1.3KG, which highly reduced the weight and space consumption of the user. HONGEN 3L/min Membrane Protable Oxygen Generator was also designed with LED Panel for easier control and display. Therefore, it was integrated with build-in battery which allow it to last up to 8 hours, to bring convenience for on the go usage. Nevertheless, it had been strictly manufactured based on a high quality foundation which makes them to maintain the enhanced quality, durability, performance and simplicity in mind comparing to the powerpluged Oxygen Generator. The design was specify on portable and durability best suitable for indoor and outdoor usage.Specification:Technical parameters: ambient humidity: 95% RH ambient temperature:-30 ~+40 Technical parameters: operating voltage: DC12rated power: 15Wmain engine weight: 1.3 kg working noise: 42dB(A) oxygen concentration: 90 +3 oxygen flow rate: 3(N)L/minoxygen production principle:MAS membrane air separation
